om 18.5miles to 22 miles on grades of i per cent. The weight of the motor cars, including the electrical equip-ment, is 53 tons, and they are able to haul from five to seventrail cars of 10 tons and 12 tons dead-weight, at a speed of 40II I m. p. h., up grades of i in 100. Ofthe ten motor cars five are finished assaloon cars for use on express trains.The other five are fitted with second-class and third-class accommodation.Each car contains a baggage com-partment and accommodations forthe air compressor. The current collector or trolley.Fig. 22, consists of two rollers ofelectrolytic copper of 3J/^-in. diam-eter and 2-ft. 19^-in. length, insulatedfrom one another, running on insu-lated ball bearings and mounted onan insulating rod. The current istaken off by copper contacts rubbingon both ends of each roller and ledinto the cars by means of insulatedcables.

The transformers also have severalwindings, which supply the current at 14 volts for running thesmall fan-motors. MOTOR CARS AND LOCOMOTIVESThe express and passenger trains are hauled by motor cars,the freight trains by electric locomotives. The company has already decided, however, to use electric locomotives for cer- to raise and lower the trolley, and glycerine dash pots are pro-vided to control the speed of movement. Each car carries twotrolley poles, one for each direction of running. The current, at 3000 volts, is carried into the car, as alreadymentioned, by flexible cables, which, within the car, are en-cased throughout in metal
